New terms related to pelagic chalk textures are pelagic mudstone, pelagic wackestone, and pelagic packstone. The second, called allochthonous chalk, consists of chalks formed from syndepositional tectonic disruption of the seafloor, resulting in mass-movement and redeposition of chalk as turbidites and slide sheets. New terms related to ...Skeletal packstone-floatstone (SPF) beds range from packstone beds, composed of silt to fine sand-sized, grain-supported gray carbonate with a lime mud matrix, to beds of floatstone resembling the packstone beds and additionally containing 10-20% large skeletal bioclasts, whole and fragmentary. ...2.1 Penjelasan gambar klasifikasi Dunham (1962) di atas : Penamaan batuan karbonat menurut Dunham terdiri atas enam, yaitu mudstone, wackstone, packstone, grainstone, boundstone, dan crystalin.

This microfacies has a grainstone to packstone texture primarily composed of foraminifera other than fusulinids along with few fusulinids, brachiopods, bivalves and micritized grains (Fig. 4 B). The diversified assemblage of foraminifera and low matrix content indicate a moderate-energy open-marine environment. The initial inter- and intra ...Dunham classification A widely used limestone classification, proposed by Robert Dunham in 1962, which divides limestones on the basis of their texture and mud content. For limestones which retain their original, depositional texture, the main subdivisions are: lime mudstone (limestone with less than 10% grains in a mud-supported sediment); lime wackestone (limestone with more than 10% grains ...The packstone fabric implies high-energy conditions which prevail in the fore-shoal mid-ramp environment (Flügel 2004).

This wiki allows SPE’s membership to update and expand …In level-bottom carbonate habitats, brachiopods tended to be overrepresented in coarser-grained packstone and grainstone carbonate sediments in the Late Jurassic, Paleogene, Neogene, and Quaternary, and therefore underrepresented in finer-grained wackestone, lime mudstone, marl, and chalk . The proportion of brachiopod occurrences in coarser ...Limestones show packstone textures delivering benthic foraminifera (15%), bivalves (10%), gastropods (10%), nummulithoclasts (5%) and radiolarians (5%). The upper limit of this sequence corresponds to an abrupt passage from marls rich in benthic foraminifera, bivalves and ostracods to coquina limestones exhibiting a gullied base.The packstone class is divided into grain- and mud-dominated packstone because the petrophysical properties of grain-dominated packstone are according to grain size, whereas mud size controls the properties of mud-dominated packstone.

Lucia (1999) divided packstones into mud-dominated (pore spaces totally filled with mud) and grain-dominated (some intergrain pore space is free of mud) packstones. Figure 9.1 A illustrates the summary of diagenetic and porosity characteristics of a carbonate ramp during a third-order sea-level lowstand under humid climatic conditions. Because of the gentle dip of the ramp-to-basin slope, lowstand prograding complexes, featuring high-energy grainstones, can commonly form seaward of the lowstand …The packstone fabric implies high-energy conditions which prevail in the fore-shoal mid-ramp environment (Flügel 2004).
